RUBBER STAIR TREADS,
RISERS & STRINGERS
raised design
Periodically lift material to ensure proper
adhesive transfer and ensure adhesive
has not surpassed the open time –
adhesive should cover 90% of the stair
tread and riser. Clean excessive adhesive
or adhesive residue from the surface of
the material using a clean cloth or mop
and a solution of warm water and a pH
neutral cleaner. Do not use abrasive or
solvent based cleaners.
To prevent movement, dust, dirt, debris
and topical moisture in or around seams,
tape seams together after installation
using a multi-purpose masking tape
intended for flooring and hard surfaces.
Pay close attention to open times to
avoid adhesion issues. This may require
installing material in smaller sections.
8. ONE-PIECE TREAD AND RISER
INSTALLATION
Ensure step substrate is suitably prepared
prior to installation, as manufacturer is
not responsible for substrates that have
not been properly prepared and tested
for moisture. When using the Excelsior
TP-620 Pressure Sensitive Tape Adhesive
or the C-630 Contact Adhesive, be sure
to a clean dusty and/or cementitious
substrates with a damp mop or sponge
prior to installation to remove dust, dirt
and debris. Ensure adhesive is approved
for use with stair tread material and that
proper trowel type and size is used, as
manufacturer is not responsible for
any and all adhesion issues related to
improper adhesive selection or usage.
Ensure all materials have been trimmed
and all stringer materials have been
installed. Clean the underside of the
one-piece tread & riser with a clean
rag or towel and denatured alcohol or
equivalent solvent adhesive remover.
Failure to do so may result in adhesion
issues due to mold-release chemical
contamination. Prior to installing one-
piece tread and risers, the Roppe #167
Cove Stick Fillet must be installed at the
joint where the back of the step meets
the step riser. Install the Cove Stick Fillet
using the Excelsior TP-620 1" Tape or
the Excelsior C-630 Contact Adhesive.
All one-piece tread & risers must be
installed with Cove Stick Fillet. Failure to
do so may result in premature wear and
damage to the tread and or riser.
To ease one-piece tread & riser
installation, use the Excelsior TP-620
Pressure Sensitive Tape Adhesive to
install material. Use 1" TP-620 tape to
adhere tread nose, 4" TP-620 tape to
install riser portion and 9 1/2" TP-620
tape to install tread portion. Install TP-620
directly stair tread to ease installation. Be
sure to leave a 1/2" - 3/4" space on either
side of stair tread nose to accommodate
the EN-610 Epoxy Nose Filler Adhesive
and avoid adhesive cross-contamination.
Prior to installing the stair tread into
adhesive, apply a 1/4" - 1/2" bead of the
EN-610 Epoxy Nose Filler Adhesive to
the interior nose of the stair tread. Failure
to do so may result in premature wear
and damage which could compromise
egress safety.
To install stair treads, remove protective
paper from TP-620 on the tread nose and
stair tread portion of the one-piece tread
& riser and install treads onto step. Once
the tread and tread nose are properly
placed, remove the protective paper
from the TP-620 on the riser portion of
the one-piece tread & riser and form
riser material up the step rise, ensuring
there is full contact with the cove stick.
If riser does not make full contact with
cove stick, the cove area of the one-piece
tread & riser could become damaged
over time.
To prevent movement, dust, dirt, debris
and topical moisture in or around seams,
tape seams together after installation
using a multi-purpose masking tape
intended for flooring and hard surfaces.
Roll material with a hand roller or
equivalent within 30 minutes of
installation, crossing in a perpendicular
direction after initial roll. Visually inspect
installation to ensure that material has
not shifted during installation. Carefully
position riser to ensure that riser is
flush with all step surfaces. If using the
Scribed Seam Method, ensure that riser
fits snugly under the stair tread above
without over-compressing material.
Roll material with a hand roller or
equivalent within 30 minutes of
installation, crossing in a perpendicular
direction after initial roll. Visually inspect
installation to ensure that material has not
shifted and that adhesive has not been
squeezed out of joints or compressed
onto surface.
9. BUTTING STAIR TREADS
Extended length steps may require that
stair treads be butted together to create
a uniform appearance. Prior to installing
treads that are intended to be butted
together, confirm material installation
pattern per design specifications or work
order, especially when installing profiled
treads. If patterns need to be centered or
aligned, ensure that stair treads are long
enough to allow for trimming on either
side of tread and seam. If possible, try to
align seam in line with handrails or other
fixtures in order to disguise the seam.
Roppe stair treads have a an acceptable
level of thickness variation from tread
to tread. For this reason, stair treads
that are intended to be butted together
may need to be sanded, undercut, or
shimmed in order match the thickness of
adjacent treads. When butting patterned
or profiled stair treads, treads should be
trimmed so that the center of the pattern
or profile is at the seam.
Butting stair tread installations require
more preparation than standard stair
tread installation. If stair treads need to
be immediately accessible, The Excelsior
TP-620 should be used to install treads.
10. INITIAL MAINTENANCE
Ensure that adhesive has cured for
recommended period of time prior
to conducting initial maintenance.
Remove any protective coverings prior
to cleaning. Sweep, dust mop and/or
vacuum stair tread to remove any dirt,
dust or debris.
Mix 2-4 ounces of Excelsior All Purpose
Cleaner per gallon of clean, potable
water. Use a clean mop to apply cleaning
solution to floor and let stand for 5-10
minutes. Use a 22 gauge soft bristled
deck brush to scrub stair treads in order
to remove dirt, debris and any remaining
mold release chemicals. If stair tread is
heavily soiled, additional cleaning may
be required.
Use a wet vacuum or clean mop to
remove any and all excess cleaning
